Package Data

This interface represents a data store. Its different implementations store data in different physical areas, you have to use it according to the data's life span and the efficiency you need.

This data store is not already available, the APC PHP extension must be enabled for you yo use it.

This factory returns you the data store that are the best for your requirements.

This data store is not very efficient but is the only one which has an infinite life span when APC is not available.

This is a very efficient data store, but its principal weakness is that it's life span is very short, in fact it's the page's execution.

This interface represents configuration data which are stored automatically by the config manager. The storage mode is very powerful, it uses a two-level cache and the database.

This is a default and minimal implementation of the ConfigData interface.

This class manages config loading and saving. It makes a two-level lazy loading: <ul> <li>A top-level cache which avoids loading a data if it has already been done since the beginning of the current page generation. This cache has a short life span: it's flushed as of the PHP interpreter reaches the end of the page generation.</li> <li>A filesystem or shared RAM cache to avoid querying the database many times to obtain the same value.

This exception is raised when a configuration entry is load whereas it doesn't exists in the database.

This exception is raised when a not existing property is asked in a ConfigData object.

This interface represents data which are stored automatically by the cache manager.

This exception is raised when you are asking a cache entry that doesn't exist.

This class manages cache. It makes a two-level lazy loading: <ul> <li>A top-level cache which avoids loading a data if it has already been done since the beginning of the current page generation. This cache has a short life span: it's flushed as of the PHP interpreter reaches the end of the page generation.</li> <li>A filesystem or shared RAM (via APC) cache to avoid querying the database every time to obtain the same value.
